Evaluating the frequency of asymptomatic Ebola virus infection

Evaluating the Frequency of Human T-Lymphotropic Virus Type 1 Infection in Iranian Population

Background: Human T-cell lymphotropic viruses 1 (HTLV1) is endemic in specific regions. We aimed to determine the prevalence of HTLV I infection among blood donors in southeast Iran.   Methods: This cross-sectional study was conducted between April 2005 and March 2015. Sera were collected from blood donors and were tested for the presence of HTLV1 specific antibody using ELISA. Reactive sample...

Seropidemiology of Epstein – Barr virus infection among asymptomatic

Introduction: Epstein – Barr virus (EBV) is a herpesvirus which establishes a persistent life-long infection in over 95% of adults world wide. Infection is usually asymptomatic but the virus is associated with a variety of disease, including nasopharyngeal carcinoma (NPC), Burkitt’s lymphoma (BL), Multiple sclerosis MS, EBV-associated B-cell lymphoproliferative disease (BLPD), Hodgkin and non...

Ebola virus infection

Ebola virus-like particles protect from lethal Ebola virus infection.

The filovirus Ebola causes hemorrhagic fever with 70-80% human mortality. High case-fatality rates, as well as known aerosol infectivity, make Ebola virus a potential global health threat and possible biological warfare agent. Development of an effective vaccine for use in natural outbreaks, response to biological attack, and protection of laboratory workers is a higher national priority than e...

Ebola control: effect of asymptomatic infection and acquired immunity.

Evidence suggests that many Ebola infections are asymptomatic, a factor overlooked by recent outbreak summaries and projections. Particularly, results from one post-Ebola outbreak serosurvey showed that 71% of seropositive individuals did not have the disease; another study reported that 46% of asymptomatic close contacts of patients with Ebola were seropositive. Although asymptomatic infection...
